This question has Statement l and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements.
Statement- I : A potentiometer of longer length is used for accurate measurement
Statement - II : The potential gradient for a potentiometer of longer length with a given source of e.m.f becomes small.
Statement - I : The emf of the driver cell in the potentiometer experiment should be greater than the e.m.f of the cell to be determined
Statement - II : The fall of potential across the potentiometer wire should be less than the e.m.f of the cell to be determined (1) Statement - I : true, Statement - II is true, Statement - II is a correct explanation of Statement -I
(2) Statement -I is true, Statement -II is true, Statement - H is not a correct explanation of Statement -1.
(3) Statement - I : is true, Statement - II is false.
